We're not "large" if you look at number of employees, but craigslist is about 95% Perl internally.

Amazon started out as a Perl shop, and is mostly still Perl. The BBC is almost entirely a Perl shop, as is IMDb.

Mail.Ru Group, the biggest russian internet company has a lot of Perl inside its main assets (web mail, social network). MRG is also the biggest publicly traded internet company in Europe. Other big russian companies like Yandex and Rambler also rely on Perl code heavily both for new and old projects.

Blekko is Perl and XS; I believe DuckDuckGo is Perl as well.

I can add (now that I work there) WhiteHat Security to that list (though we're quite promiscuous: I've done stuff in Python, Java and Mono there as well), and an awful lot of infrastructure is done in Perl at Yahoo!.

A fair chunk of Polyvore's backend is written in Perl.  I have to add that we made a lot of effort to write super clean, modern Perl, not the mythical spaghetti it is sometimes known for.

We also have big chunks of javascript, Java and now Objective C.

In Southern California we have Ticketmaster,,, ValueClick, Shopzilla, PriceGrabber, Rubicon, MediaTemple, and Yahoo (ex-Overture) just that I know of personally.  We have lots of smaller shops too, of course.

Apple, large in terms of market capitalization, has 128 open positions[1] that reference the keyword "Perl" at the time of the writing. The positions are in areas including but not limited to: automation, build engineering, QA, web development, tools, systems administration, infrastructure and integration. Accordingly, it may be reasonable to conclude that Apple, while not using Perl for the underlying architecture of core products and services, does use Perl (amongst a great many other technologies) as part of the underlying architecture of various internal systems and processes which are in support of their core products and services.

Grant Street Group, large in terms of auction volume, recently surpassed 11 trillion USD[2]. Perl is the implementation language of their flagship platform.
